Hey Erin...

If the sensations have changed since you saw your neuro I would put a call in and see what he thinks...

As far as the "I don't want to go to sleep cuz something might not be working when I wake up feeling". I am pretty sure that thought runs through my head every night... It is very scary and you just don't know.

When I was first having symptoms I had the numb arm and shoulder blade that started in my fingers and moved up. So yes it is possible. Hope you feel better soon.

Take care!
